EDWARD FALES, OF ST. LOUIS, MISSOURI.

WINDOW AND DOOR SCREEN.

SPECIFICATION forming part of Letters Patent No. 319,685, dated June 9,1885.

Application filed July 19, 1884.

To aZZwhom it may concern.-

Be it known that I, EDWARD FALES, a citizen of the United States, residing at St. Louis, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in Vindow and Door Screens, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in window or door screens, the object of which is to prevent flies and other insects from coming into the room or apartment, while at the same time it will permit the insects which happen to be in the room when the screen is put up, or those which enter the room through the door or from the adjacent rooms, to passout into the open air.

My invention consists in making the screen of two or more strips of wire-netting or other suitable material, which overlap at the edges, the overlapping edges being separated by V-shaped or diagonallyplaced pieces of wire, between which are left open spaces or passages through which the insects are permitted to pass to the outside of the building, as will more fully appear.

Referring to the drawings, Figure 1 is a front or side elevation of my improved screen as applied to a window. Fig. 2,is a sectional view showing the overlapping edges with the interposed pieces of wire. Fig. 3is a detached View of one of the wire strips.

In the drawings, A indicates an ordinary window-frame, in which is secured my improved screen in any suitable or convenient manner.

B is the frame of the screen, and O is the screen, which is composed of wire gauze or netting in the following manner: The wirenetting or other material of which the screen is composed is cut into strips, D, of any suitable width, so that two, three, or more strips will form a screen for an ordinary window, the number of strips being increased for larger windows or for screen-doors. The strips of netting are secured to the frame B by means of nails, or in any suitable manner, so that an upper strip will overlap the upper edge of the strip below it a short distance on the inside, the overlapping portions being separated by (No model.)

ping edges of the strips of netting, and at the same time to form passages through which the flies or other insects can pass from the room,

short pieces of heavy wire or othersuitable material, E, are secured in a diagonal position at each side of the screen, as shown.

V-shaped pieces of wire or other suitable material, F, are also secured to the upper edge of the strip, as shown, leaving small openings or channels 1) between each set of bent wires, through which the insects can pass out into the open air. It will be noticed that the spaces between the wires at theirlower ends are wider apart than at the top, which prevents the flies from entering the room from the outside.

The wires or strips E F- may also be made thicker at the bottom than at the top, thus gradually contracting the walls of the chambers or passages from the bottom to the top, and more effectually prevent the flies from entering the room through these channels.

The pieces of wire or other material are soldered, glued, or otherwise secured to the body of the screen or to the strips of netting, as described, to separate the overlapping edges, and also serve as guides or deflectors to direct the insects out of the room. The second strip of wire-netting or other reticulated material is secured in the frame B so as to overlap the upper edge of the lower section as far down as the lower ends of the pieces of heavy wire, to which it is secured by solder or in any suitable manner.

The pieces of wire E F are of sufficient thickness to hold the strips of fabric far enough apart to permit a fly or other like insect to crawl up on the inside of the screen and pass out between the sections of netting, while the diagonal sides of the pieces E F serve to direct the insect out through the openings 6.

Itis a well-known fact that when a fly alights on any section of the screen, the natural tendency is to crawl upward, and in doing so passes out between the sections of the screen into the open air.

I do not wish to limit myself to wire-netting separated at the lap portions by means of 15' short wires inclined alternately in opposite directions, the lower ends of which are brought together, while a space is left between their upper ends and rigidly fastened to the netting, whereby V-shaped passage-ways are 20 formed between the sections.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD FALES.
